Living with an odor condition has not been easy. For years I lived a life of a hermit, afraid of the way people would treat me if I stepped outside of my front door. Tomorrow is another day. I will be fine. So we ate breakfast at a restaurant this morning before leaving on our trip. A few minutes later as we were seated, I see one of the waitresses go outside and walk around to the window we were facing and she stood there staring at me. I stared her down. Then I winked at her…She rolled her eyes and pinched her nose.
Methylotrophic Bacteria in Trimethylaminuria and Bacterial Vaginosis
Trimethylaminuria is a disorder in which the volatile, fish-smelling compound, trimethylamine TMA accumulates and is excreted in the urine, but is also found in the sweat and breath of these patients. Because many patients have associated body odours or halitosis, trimethylaminuria sufferers can meet serious difficulties in a social context, leading to other problems such as isolation and depression.
Primary trimethylaminuria sufferers have an inherited enzyme deficiency where TMA is not efficiently converted to the non-odorous TMAO in the liver. Secondary causes of trimethylaminuria have been described, sometimes accompanied by genetic variations.
To date, no treatment modifying the disorder exists and only a few TMAU has thus been referred to historically as fish odor syndrome. blockage of adhesion sites for pathogenic bacteria, degradation of toxins and blockage.
Important It is possible that the main title of the report Trimethylaminuria is not the name you expected. Trimethylaminuria is a rare disorder in which the body’s metabolic processes fail to alter the chemical trimethylamine. Trimethylamine is notable for its unpleasant smell. It is the chemical that gives rotten fish a bad smell. When the normal metabolic process fails, trimethylamine accumulates in the body, and its odor is detected in the person’s sweat, urine and breath.
The consequences of emitting a foul odor can be socially and psychologically damaging among adolescents and adults. The genetic or primary form of this disorder is transmitted as an autosomal recessive trait. The metabolic deficiency occurs as a result of a failure in the cell to make a specific protein, in this case the enzyme flavin-containing monooxygenase 3. Enzymes are nature’s catalysts and act to speed up biochemical processes. A secondary form of trimethylaminuria may result from the side effects of treatment with large doses of the amino-acid derivative L-carnitine levocarnitine or choline.
This secondary form of the disorder is a result of an overload of trimethylamine. In this case, there is not enough of the enzyme to get rid of the excess trimethylamine.

A lack of active FM03 means affected individuals cannot convert odorous trimethylamine TMA , produced from breakdown of dietary choline by gut bacteria, to the non-odorous N-oxide. Social isolation, ridicule and limited employment prospects are experienced by those with TMAU, which translates to a low quality of life; high levels of depression, suicide and divorce occur in this population.

Study record managers: refer to the Data Element Definitions if submitting registration or results information. Many yet uncharacterized medical conditions including inborn and acquired errors of metabolism or skewed microbiome could be responsible for unpredictable and uncontrollable episodes of body odor and halitosis. These conditions have dramatic impact on the quality of life and socioeconomic outcomes of sufferers. Yet clinics and specialized malodor centers do not provide tests for diagnosing malodor other than trimethylaminuria TMAU.
Self-reported odor problems are often dismissed if are not organoleptically evaluated by trained odor judges that are not readily available during malodor flare-ups. The aim of this study is to analyze effectiveness of existing gastrointestinal and nutritional tests for the assessment and investigation of self-reported malodors. Values measured by the laboratory Biolab Medical Unit will be compared against the reference range specific to that laboratory.
Principal component analysis PCA allowed to clearly separate data into two clusters “Sour” and “Sweet” shown below along with the “Lactic” subgroup from the “Sour” group.

Just before Rare Disease Day , a study from the Monell Center and collaborating institutions provides new insight into the causes of trimethylaminura TMAU , a genetically-transmitted metabolic disorder that leads to accumulation of a chemical that smells like rotting fish. The findings indicate that genetic testing to identify mutations in the FMO3 gene may not be sufficient to identify the underlying cause of all cases of TMAU.
TMAU is classified as a “rare disease,” meaning that it affects less than , people in the United States. However, its actual incidence remains uncertain, due in part to inconclusive diagnostic techniques. Reed, PhD, a senior author on the study. The socially and psychologically distressing symptoms of TMAU result from the buildup of trimethylamine TMA , a chemical compound produced naturally from many foods rich in the dietary constituent, choline.
Such foods include eggs, certain legumes, wheat germ, saltwater fish and organ meats. TMA, which has a foul, fishy odor, normally is metabolized by the liver enzyme flavin-containing monooxygenase 3 FMO3 into an odorless metabolite. The TMA, along with its associated unpleasant odor, then accumulates and is excreted from the body in urine, sweat, saliva, and breath.
This led the researchers to suspect that other genes may also contribute to the disorder. In the new study, reported in the open access journal BMC Medical Genetics , the research team combined a gene sequencing technique known as exome analysis with sophisticated computer modeling to probe for additional TMAU-related genes. The study compared sensory, metabolic and genetic data from ten individuals randomly selected from subjects previously evaluated for TMAU at the Monell Center.
Each subject’s body odor was evaluated in the laboratory by a trained sensory panel before and after a metabolic test to measure production of TMA over 24 hours following ingestion of a set amount of choline.

Trimethylaminuria TMAU is an uncommon condition that causes an unpleasant, fishy smell. It’s also called “fish odour syndrome”. Sometimes it’s caused by faulty genes that a person inherits from their parents, but this isn’t always the case.
Trimethylaminuria symptoms can be present from birth, but they may not start until later in life, often around puberty. The only symptom is an unpleasant smell, typically of rotting fish — although it can be described as smelling like other things — that can affect the:. They can check for more common causes, such as body odour, gum disease, a urinary tract infection or bacterial vaginosis. Tell your GP if you think it might be trimethylaminuria.

The purpose of this study is to identify microbial signatures associated with remission and recurrence of idiopathic malodor and PATM conditions. Human odorprints, mostly owing to the microbiome, have proven their value as biomarkers of health and environmental exposures. In recent years, microbial networks responsible for localized malodors such as halitosis or axillary odor have been mapped by using next generation sequencing approaches.

The origins and metabolic transformation of trimethylamine TMA in the human body are summarized, and its role in pathological conditions described. The principal pathological conditions are 1 trimethylaminuria, an inherited metabolic condition preventing conversion of malodorous dietary TMA to trimethylamine-N-oxide TMAO , 2 dimethylaminuria, a metabolic deficiency resulting in TMA production as a result of the incomplete metabolism of dietary TMA-compounds; and 3 bacterial vaginosis, characterized by excessive TMA production, principally from the microbial reduction of TMAO.

Another inborn error of metabolism accompanied by fish-like body odor results from deficiency of dimethylglycine dehydrogenase see Trimethylaminuria results from the abnormal presence of large amounts of volatile and malodorous trimethylamine within the body. This chemical, a tertiary aliphatic amine, is excreted in the urine, sweat ichthyohidrosis , and breath, which take on the offensive odor of decaying fish Mitchell, Individuals with trimethylaminuria excrete relatively large amounts of amino-trimethylamine TMA in their urine, sweat, and breath, and exhibit a fishy body odor characteristic of the malodorous free amine, leading to the designation fish-odor syndrome.
TMA is a product of intestinal bacterial action. The substrates from which it is derived are choline, which, bound to lecithin, is present most abundantly in egg yolk, liver, kidney, legumes, soy beans, and peas, as well as from trimethylamine-N-oxide, a normal constituent of saltwater fishes.
